18 Great Cardio Workouts That Don't Require Running

Jumping jacks don't require any equipment, you can do them anywhere, and they are so simple they do them in elementary school gyms. "Do them the standard way — arms going overhead — or cross your arms over your chest to improve shoulder flexibility," says Corkill "It gets the upper body involved as well as lower, whereas something like cycling only uses your leg muscles." Corkill likes to add quick bursts of jumping jacks throughout a workout to spike your heart rate.
